IMPROVEMENT IN PLOWS.

Specification forming-part of Letters Patent No. 164,730, dated June 22,1875 application filed May 1, 1875. v

To all whom it'may concern:

Be it'known that I, AUeUsrUs Gnrees, of La Fayette, in the county ofMacon and State of Tennessee, have invented a new and useful Improvementin Flows, of which the following is a specification Figure 1 is a'sideview of my improved plow. Fig. 2 is a top View of the same. Fig. 3 is adetailed view of a modified form of the cutter and brace.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved plow, strong anddurable, yet peculiarly simple in construction.

The invention consists in the combination of the standard, made with aconcaved shoulder or offset upon the forward side of its lower part, themold-board, the point, and the cutter, as hereinafter fully described.

Ais the plow-beam, to the rear end of which the standard B is framed.The standard B is made with an offset or shoulder, to rest against thelower side of the beam A. The forward side of the standard B is concavedfrom its shoulder or offset to its point, to form a seat for the moldboard 0. The plow-point D is attached to the lower end of the standardB. E is a cutter, the upper part of which passes, up' through a mortisein the forward part of the plow-beam A, and is secured in place by pins0, passed through it above and below the said beam. The lower end orpoint of the cutter E should extend into the ground deeper than theplowpoint D.

The cutter E may be used or not, as may be desired.

F is a cutter that passes through a m0r tise in the beam A, the mold-board 0, and

.the standard B, and is secured in place by pins f, passed through itabove the beam A and below the standard B, as shown in Figs. 1 and 2.Seyeral holes are formed through the cutter F to receive the pins f, sothat the cutter maybe adjusted higher or lower, as may be required. Thelower end of the cutter F projects so as to enter the ground to anydesired depth.

The cutter F acts as a cutter, and also as a brace, to strengthen thestandard B against the draft-strain. The cutter F may be made without adownwardlyprojecting point, as shown in Fig. 3.

G is a subsoil-plow, the standard of which passes up through thestandard B and the beam A, and is secured in place by pins 9, passedthrough it above the beam A and below the standardB. Several holes areformed through the standard G to receive the pins 9, so that thesubsoiler may be adjusted to work deeper or shallower in the ground, asmay be desired.

The parts of the-beam A and standard B against which the pins 6 f g restare faced w1th'iro n, to prevent wear.

The subsoiler Gr may be used or not, as may be desired.

Hare thehandles, the forward ends of which are secured to the oppositesides of the middle part of the beam A. The upper parts of the handles Hare attached to the endsof the round I, that passes through and issecured to the upwardly-projecting end of the standard B.

If desired, the handles H maybe secured to a round passing through thestandard B just above the beam A, and their forward ends may be securedto.the said standard B just above the plow.

The round I may pass through the standard B, through the mortise thatreceives the tenon of the beam A, or above or below said mortise.

The standard B may terminate just above the beam A, or may project toany desired extent. 7

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the standard B, made with acoucaved shoulder or offset upon the forward side of its lower part, themoldboard G, the point D, and the cutter and brace F, with the beam A,in substantially the manner herein shown and described.
